Scientists Say That Uranus Appears to Have a Girlfriend

When checking out Uranus, scientists discovered something exciting: that the planet appears to have a long-term... well, call it a situationship. In a new, yet-to-be-peer-reviewed paper flagged by Universe Today, an international group of researchers detailed finding a so-called "Centaur" — a small, icy and rocky body that sits between Uranus and Neptune and is designated as a minor planet — that appears to have been keeping up with Uranus in a delicate cosmic dance for thousands or even millio

Uranus Leaks More Heat Than We Thought

When Voyager 2 flew past Uranus in 1986, the spacecraft detected a surprisingly low level of internal heat from the planet. Since then, scientists believed Uranus to be the odd one out in our solar system’s family of giant planets—the others being Jupiter, Saturn, and Neptune—who all tend to emit more heat than they absorb from sunlight. Now, a new study suggests that scientists may have had the wrong idea about Voyager 2’s data: Uranus does have an internal heat source similar to its planetary

A Closer Look At Uranus’s Moons Reveals a Surprising Dark Side

The moons that orbit Uranus are already known to have unusual characteristics: some are heavily cratered, others have tectonic features or a patchwork of ridges and cliffs. Using the Hubble space telescope, scientists took a closer look at the surface of Uranus’s four largest moons and discovered something rather unexpected. For the study, a team of astronomers went searching for signs of interactions between Uranus’s magnetic field and its four largest moons: Ariel, Umbriel, Titania, and Obero
